Checking the power steering

Checking fuse




- Ignition off.
Check that fuse 11C/32 (10A) is intact.

Is the fuse intact?

Yes - Checking ground wire

No - Checking the wires

-------------------------------------------------

Checking ground wire




- Ignition off.
- Remove connector from power steering.
Check the wire between power steering (6/71) connector 6 and ground point 31/93 for an open circuit as described in Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Do the necessary corrective action.
